MouseTracker software enables real-time psychological task analysis using computer mouse movements. This method reveals cognitive processes through hand motor dynamics, offering researchers detailed insights into decision-making.

Area of Science:

  • Cognitive Psychology
  • Human-Computer Interaction
  • Psychological Research Methods

Background:

  • Traditional psychological research methods often lack real-time, fine-grained data on cognitive processes.
  • Assessing the dynamics of mental processes during decision-making requires innovative approaches.

Purpose of the Study:

  • To introduce MouseTracker, a novel software package for real-time cognitive process assessment.
  • To enable researchers to analyze cognitive dynamics through computer mouse tracking.

Main Methods:

  • Utilizing a computer mouse-tracking method to record x, y-coordinates at 60-75 samples/sec.
  • Developing and running experiments within a user-interactive, graphics-based environment.
  • Analyzing mouse trajectories for measures of spatial attraction, curvature, velocity, and acceleration.
